Fire resistant glass unit

摘要

Flame retardant glass has two panes arranged at a distance from each other, where the flame-sided pane is a glass pane and a foamed intermediate layer is arranged in the space between the panes. The intermediate layer is made of sodium silicate glass and water and has an additive increasing the resistance time in the case of a fire, which is displaced with multivalent alcohols and/or sugars. The novelty is that the sodium silicate glass as additive to the intermediate layer to suppress the sensitivity of the intermediate layer towards UV radiation is chosen so that there is no more sensitivity towards UV light.
